Create an android project in the android studio ( Android First Program in Android Studio) Step 2. * A fragment that launches other parts of the demo application. Let’s start building basic: How to pass data between fragments.

This is the most rudimentary example (display map, move camera and display marker) and can be run from any other activity:Ĭopy raw styler package // change to your own package add(int containerViewId, Fragment fragment): adds a given fragment to activity state. In this example, I'm going to add the map as a fragment. Embrace the Zen of deleting code You’ll replace it with the list of dog breeds.

First, open activitymain.xml again and remove the you inserted.

You will see the fragment: Adding a Fragment Dynamically. I wanted to change my previous example so that the homepage of the app (the starting page) will simply display a button to the map (in case of offline mode or incompatibility with the device). By including this in the XML, the FragmentManager knows to add this fragment to the activity automatically. The previous article meant that the Google map was your main activity and any other activity would be a sub-activity returning to the map activity would restart the app as a menu item, it would need to launch a new intent. Note that this article is based on a new blank project which does not include code from the previous example but you can still build this over the previous example (as I did).

A sequel to my article ' Basic Android App using Google Maps and Current Location', this article suggests how to add Map as a sub activity.
